The reason why we're sending Fabio out on loan is that he will get some first team experience in the PL, and hopefully will come back and compete with Evra for a spot in the XI rather then just be a backup. We dont need anyone to replace Evra at the moment, but rather have someone who can play at left back in league cup matches, or someone who can be subbed on for the last 20 minutes of a game.
If Fergie and the entire coaching team believes that Brady can be that person while Fabio is out getting his experience somewhere else, who are we to say that it's cant be done? I'm pretty sure that they've seen the player a hell of a lot more then anyone on this forum, and then to argue that something can't be done?
I doubt that we'll go for Baines, as it seems to me that Fergie believes in Fabio and that we only need someone to cover for Evra whilst Fabio is getting some gametime somewhere else. Not someone who'll replace Evra all together and put Fabio even further down the line for a first place spot. We want to give Brady some Premier League experience aswell, and it's obvious that they believe that he's capable of playing left back, so why pay some old guy to do the job that a young, talented player who've been with the club for many years can do?
